Hi guys, i am new to this forum and am not very smooth in navigating my ways so i apologize if this has been covered before.I own an e class 350 coupe , bought it last march. So my question is, i just bought a smoked amg side marker housing just to pimp up my car's look since its white and i thought it would go well with the smoked side markers...So i tried to remove the current holster and the orange cover came off, this made it possible for the current housing to be taken out but since the smoked one is still intact, i cant seem to put it back in...It would be great if anyone here can tell me how to do it right..

Thanks in advance
